Overview of DiskPart Command Line

DiskPart is a disk partitioning program designed to manage disks or partitions. When we focus on disk management tools, Diskpart is one of the common partition helpers we choose, featuring creating partitions, merging partitions, extending partitions, and deleting partitions. As a built-in utility, it has more powerful features that Disk Management can not solve, such as setting mirrored volumes... Once the command line is setting up, there is no way to go back.

Basic Command-Line of DiskPart

  • Create - Create a partition or a volume.
  • Active - Set disk partition as active.
  • Clean - Remove all partitions from the existing disk.
  • Extend - Extend partitions with unallocated space.
  • Format - Format disk or partition to free space.
  • Shrink - Modify the partition size.


How to Use DiskPart

  • Take "Create partition" as an example:
  • Type DiskPart in the search box > Once it pops up, right-click it and choose Run as administrator.
  • Input each command line and hit Enter:
  • Type list disk > Select disk * (* stands for your targeted disk number.)
  • Type create partition primary size=* (* shows the partition size you want.)
  • Type exit.

Even though DiskPart requires many features to manage disk or partition, it still contains some error messages when you are trying to extend or format partition, like "The volume is too big." So, to fix Diskpart not working issue and get a better partition performance, we've listed some free DiskPart alternatives here. Figure out the pros and cons of each software and download the one by preference.
